Can I ask a few newb questions on tuning?
All the info I learned from tuning has come from this site, but their are a few things I am not clear about. Now I have a 14 BRZ, with an axle back, drop in filter, and a Perrin intake tube. That is considered stock, so I would need the ECUTEK 1 tune correct?

I have nothing, so I would need the ECUTEK, the cable, and the license, I am just confused on what exactly the license is, and what do I do with it. I know its not s literal license but still. I am not sure what its benefit is for the installation.

After purchasing this what happens if I do more mods and I want to do a stage 2 tune? Would I need to buy it again? Is there a way to just add it to the tablet I will have already owned?

And last question once I have everything, the tune is fairly simple to do right? You just plug it in, start the car on ACC II (engine off) and follow the directions right? Or am I wrong? Thanks in advance for all answers.

Of course you can ask questions, you came to the right place - :thumbsup:

However, you got a hold of the wrong guy - I know nothing about "tuning" these cars - :(

But, if I understand correctly, the "mods" you mentioned above, do not require the engine be tuned with an aftermarket tune.

Now, folks will come along shortly to help you out - ;)

Just do it yourself

Another reason why it's not worth modding in Cali

To this date. The 2.076 are the best oft tunes.

Unless you have a 2017 or newer car :-)

with your mods I would just get an OFT which you get stage 1 and 2 tunes for free on it. If get catless headers than you can use the stage 2 on it , or sell it then step up to ecutek

The license just allows you to use the ecutek tuning program on your car. The license, cable, and dongle are a one time purchase you don’t need to keep rebuying. If you change your mods and need a new tune you will need to either purchase a tune revision if it’s a “simpler mod” or a new tune all together.

You need a laptop to flash the tune to the car. The steps are pretty straight forward and easy. They will give you noob friendly step by step instructions. Most of the actual tunes for ecutek come with atleast one free revision so it will be more dialed in then a ots tune.

But depending on your future mod plans OFT could be a cheaper solution with almost as good results. Good for basic mods and “common” headers. But not recommended if going FI unless you know how to tune yourself.

Thanks for the replies guys. Much appreciated! I’m gonna look into OFT now. Thanks again

Update for anyone that might be curious. I've been running the E85 stg 2 tune from oft with a hi flow catted uel header and magnaflow catback and it is running great. Only issue I've had is cold starting in the mornings which I hear is a normal thing running E85 in the winter. But I'm super happy with what the tune provided. If anyone is looking for an easy and cheap reliable tune I would recommend it until you want to go for some heavier mods like boosting and such.

I have a guy selling sti injectors. I'm a noob to fuel stuff, are our injectors top feed or side feed? Want to know which ones I can pick up

Side

I'm thinking of going back to my stock FRS muffler from my Nameless track muffler because of the noise. Does anyone know how much horsepower I would lose if any.

Almost none, the stock catback flows pretty well.

How are Subaru dealers if your car is tuned for warranty claims?

Terrible regardless of tune.

Mine's pretty good, they pulled my motor for an oil leak under warranty, even though the car had a header and tune on it. Every dealer is different.

Oh man reading this exchange. You explained perfectly well from the start. Other guy was not reading though he was trying to be helpful

'17+ Update?
 

With the improved header in the '17+ cars, what happens to the "+5-8hp" gain, over a tune on stock header scenario? Seems like going to a UEL catless header will get me more/different sound, some improved mid range, possible inspections issues (in Texas?), but little, if any (or loss of) peak HP? From a peak HP standpoint, given the improved OEM header, seems like I'm better off just getting a tune for the stock system I'm running with Nameless axleback...which is already at the max noise level for me. With the improved fueling mentioned in the '17+ cars, are the gains of ~10hp for a tune alone also diminished with the '17 updates?

You're probably right. Dont spend a grand for a little more torque. A good tune is probably your best bet

Steve mentioned the '17+ cars got new header AND fueling, so what's left of the ~10 hp for '13-'16 cars, tune only, after the factory changes?

200 whp give or take is the limit with the fa20. Pre 17 benefit more from an aftermarket header as they are less efficient from the factory.

Awesome to have this reference available. I think Steve99 should write a book. This is some of the most useful information I've seen on any online motorhead forum, over the last 20+ years. :)

No inspection issues with tune.. no light, no code, no worries. You hold out I'll be parting with my Tomei UEL and overpipe .. two pieces are very nice.. wrapped already too.. throw the stock back behind the front pipe like you said you were thinking of doing and you'll have a stock rumbler with maybe a little more low end and little less dip even for 2017+.. and I'm from the same area

What are you replacing the Tomei with? I ordered a Gruppe S UEL catless and a Perrin 2.5 resonated catback, so I'll probably have my Nameless axleback for sale. I'm thinking of the OFT tune, and maybe finding some help reviewing the logs.

I'm about set on a JDL turbo or SPD 500x (especially if I find solid OFT tune for it that'll work on 93 octane.. The tomei UEL header and overpipe is super nice. I'll miss them. Mainly why I'm going with JDL over some others to get that UEL. I have a Borla catback which real throaty but smooth and goes well with it.. I'm sure the Perrin would too.. if I do this I'll replace the front pipe with 2.5 Avo high flow cat that I just happen to have (woo hoo) and 2.5 JDL overpipe..

Was going to mention anybody in software tuning can help you look at logs .. just have to dump the CSVs in datazap website .. easy to do PM me if you have questions .. might have to change a couple of the default params that oft sets again super easy

My question is about tuning 2017+. I didn't see anything quantified in earlier posts. I had a 2014 BRZ with UEL header and tune and made 193WHP (+15% from OEM). But had an accident at the track and looking to get another BRZ. I see from this thread that 17+ have some differences. Which car will make more power after header and tune, a 2016, or a 2020? I had heard that the 17+ and the 2020 in particular didn't benefit much from tuning and that a 2016 after tune will produce more WHP and torque than a tuned 2020. Is this true? Or do they both end up in the same place - just that the 2017+ starts out more efficient so less percentage gain?

OpenFlash tune V2
 

Does anyone know if the software on the OFT V2 is compatible with new 2020 BRZ's?

I have a V1 and it works with my 2020.

You may have to email them for you CAL ID, if it isn't already listed on their site.

Mine was not, but I received it in a couple days.

I just installed Skunk2 EL Catless Headers, I have a Greddy SP Elite Axleback, and did the stage 2+ tune, would it make a difference if I upgraded to a full catback exhaust, like an Invidia Q300 for example? Thanks

Nah

Thanks dude, really didn't wanna spend the money on a new exhaust if I didn't have too.

Catless FP will get you a couple more ponies.

A catback will make you sound like you got a couple more ponies.

Thanks! I'll keep my axle back then.

So my Mrs Brz Ts 2018 with Q300 CB for sound and a OFT tune will be pretty good?Not sure here I`m used to Wrx

Fitted PSR catless header and O/pipe, stock front pipe, Q300cb and OFT e85 V4.xx tune. Sounds great and pulls from low rpm getting stronger as revs increase
